Abstract
The invention discloses a novel compensation mechanism for an oil press, wherein a main engine of the oil press consists of a top beam of the oil press, a telescopic beam, an operating platform, a double-acting pull pillar and a main oil cylinder; and the bottom of the operating platform is provided with a compensation hydraulic cylinder, an oil inlet of each compensation hydraulic cylinder is connected with an outlet part of an integrated electric pressure control valve in parallel, an oil inlet of the integrated electric pressure control valve, an oil inlet of the main oil cylinder and an oil outlet of a pressure source are connected with one another in parallel, a pressure sensing system is connected on the pressure source, and the pressure sensing system is connected with the integrated electric pressure control valve in parallel by the pressure source.
Description
Technical field
The present invention relates to a kind of hydraulic press compensation mechanism, particularly a kind of novel hydraulic press compensation mechanism belongs to the hydraulic press technical field.
Background technology
Hydraulic press is made up of walking beam, built-in beam, base etc., because the body of hydraulic press is big, the spacing span is big; Heavy Weight is in order to bear bigger moment of flexure, general also corresponding do higher of the effective depth of walking beam, built-in beam and base; So under the operating pressure parameter that communicates, hydraulic press other uniform pressure parameter machinery is relatively compared; Its appearance and size, especially height dimension are higher, can not satisfy in place, less space and use.
Summary of the invention
The objective of the invention is to: a kind of novel hydraulic press compensation mechanism is provided, overcomes that the prior oil pressure machine is existing can not to be satisfied in the employed defective of less spatial field.
The technical solution adopted for the present invention to solve the technical problems is: a kind of novel hydraulic press compensation mechanism; It is made up of hydraulic press back timber, extensible canopy, workbench, two moving stay column, master cylinder, compensating hydraulic cylinder, integrated electric pressure-control valve, pressure source, pressure capsule system, main frame, and the hydraulic press compensation mechanism has the hydraulic press main frame that is made up of hydraulic press back timber, extensible canopy, workbench, two moving stay column, master cylinder; Be provided with a compensating hydraulic cylinder in the bottom of workbench; The oil-in of each compensating hydraulic cylinder is connected in parallel on the export department of integrated electric pressure-control valve; The oil-in of integrated electric pressure-control valve and the oil-in of master cylinder and the oil-out of pressure source are in parallel; On pressure source, be connected with pressure capsule system, pressure capsule system is in parallel through pressure source and integrated electric pressure-control valve.
Beneficial effect: because the present invention has adopted such scheme, when the load of hydraulic press increased, the operating pressure of master cylinder increased accordingly; Thereby the heap(ed) capacity of load is passed on base, and base will add aximal deformation value with the increasing of load, still; Pressure capsule system is controlled the electron pressure valve through the control system according to detected pressure size, and compensating cylinder will award compensation through corresponding pressure oil; Because pressure and master cylinder that compensating cylinder produced are in the opposite direction, so, offset master cylinder and acted on the surging on the base; So; The present invention can reduce the height of complete machine, can satisfy in less place, space and use, and has effectively overcome existing hydraulic press and can't satisfy in the employed defective of less spatial field.
